The future: #JusticeLeague feels like a new start to the age of heroes and succeeds as a launch platform in that, even though some of its newer characters very much would have benefited from origin stories beforehand.

I have a lot to say about ‘Justice League’ but will wait till it’s released to really get into it. But two important things to know: stay till the very end of the credits and Jason Momoa (@PrideofGypsies) is awesome as Aquaman. pic.twitter.com/Pg6cKCZAEo

Justice League is the super heroes we've been waiting for. Aquaman rocks. Cyborg is bad-ass. The Flash is awesome. Wonder Woman builds from an already great standalone. Batman assembles them and it's great.

#JusticeLeague is better than BvS and #SuicideSquad – it's lean, mean & packed w/ superhero action. I dug most of its lighter moments & I think it has one of the best action sequences ever in a DCEU movie. And of course Wonder Woman steals the show. pic.twitter.com/rW3UjpBUMk

JUSTICE LEAGUE! It's okay. Narratively it's a mess, the stakes don't work & the villain isn't great. HOWEVER, the heroes ARE great, it's funny, & there's some surprisingly effective character work. I didn't love it, but there are enough good pieces to excite me for the future. pic.twitter.com/OY4ARJ5vDY

#JusticeLeague is fine. It's more coherent & less idiosyncratic than Batman v Superman (which I loved, so make of that what you will), and tries very hard to lighten up on the gloom & doom of the DC universe. There are jokes and everything!

#JusticeLeague is a fun blockbuster that is entertaining enough to overcome its flaws. The team works well together to deliver more than a few spectacular superhero moments worth seeing on the big screen.
